Arrnnnfrus non MAKING BISULPHITE Menon.

Application led Hay 4, 1927, Serial No. 188,737, and in Canada September 23, 1926.

i The invention .relates to an apparatus for making bisulphite liquor, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

rllhe invention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelt-y following a description containing an eX- planation in detail of an acceptable form of the invention.l The objects of the invention are to furnish means for regulating the flow of gas and water to and from the towers; to form a method whereby the flow of gas and water may be reversedvif desired; to construct an apparatus for the purpose of gas absorption processes and the like in which the continuous operation need not be interrupted in the ordinary'course of events; to regulate the percentage of free sulphurdioxide in the linished acid liquor and generally to provide a plant showing an eilicient circulation system of the gas and liquor that may be readily reversed r from time to time and that 'will utilize the sulphur gas to the very best advantage in the production of the finished acid liquor.

1n the drawings, Figure 1 is a vertical secous connections.

\ Figure 2 is an enlarged sectional detail 1n perspectiveof the four way valve as used in this invention. v

lFigure 3 is a plan view partly in section of the tour way valve.

'Figure 4 1s avertical sectional view ot the six way acid cock. L

Figure 5 is a plan view partly in ysection of the six way acid cock.

Like numerals of reference indicate corresponding parts in the various figures.

Y Referring to the'drawings, the towers 10 and 11 form part of a circulation system through the upper and lower gas pipes 12 and 13 and 14 and 15 respectively, the flow of gas being directed in regard to the upper gas pipes 12 and 13 by the four way valve 16, and the flow of gas in regardto the lower gas pipes 14 and 15 being directed by the four way valve 17. These two valves 16 and 17 are connected b lthe gas pipe 18.

The lower'va ve 17 is connected to the gas inlet pipe 19, which is connected to a sulphur burner, and the upper valve 16 leads to the tional view of the towers showing the varig exhaust pipe 20 to the 'atmosphere and extendlng upwardly from said valve 16.

Each of the tour yway valves .16 and 17 comprise the valve plate 21 made integral with the end circular plates 22 and 23, the circular plate 22 having the projecting lug 24 secured in the bearing 25 in the stationary plate,26 and having the indicator 27 adapted to be moved between the two indicatorlugs 28 and 28?, this plate 26 being secured tothe housing 29 oi the valve.

'lhe apparatus is here shown with two towers 10 and 11, though this invention is not limited to any particular number so long as the salient features are included. A quantity of limestone in pieces customarily -used in such processes is supported in the tower 10 on the upper grate 30 and in the tower 11 on the upper grate 31 and above the limestone in the tower 10 the spray box 32 is situated and similarly in the tower 11 the spray 33.

The lower grates 34 Iand 35 are situated in the towers 10 and 11 respectively at reasonable distance above the bottom and spaced from the gratos and 31 and support the blocks of hard wood, tile, rings or other insoluble material which ll up the greater part of the space between the upper and lower rates.

'llhe water inlet pipe36 connected to a suitable source of water supply feeds through a six way acid cock 37 comprising the valve 38 formed of the plates 39 and 40 and 41 ha angular formation in relation to one another and integral at each end with the circularl rotatable plate 42 and 43 and contained in a housing 44. @ne of the rotatable plates 42 has a projecting lug 45 extending throughthe hole 46 in a removable cover 47 and this lug 45 is secured to the indicator lever 48, said indicator g48 being movable between two stop lugs 49 and 50. The removable cover 47 has the projecting crown'51 adapted to engage between the housing 44 and plate 42, and having the packing 53 and 54, andis adapted to be bolted by a plurality of bolts 55 to the housing 44.

From this sin way acid cock, the pipes 57 and 58 are connected to the water pun-ips 59 and i60, the pipes 61 and 62 are connected to the towers 10 and 11 respectively, the pipe 63 is connected to the acid storage tank 64, and

the pipes 65 and 66 are cnnected to the tow;` ers through the pumps 59and60.

ln one form of operating of the apparatus, the gas flows through the inlet pipe 19 into the valve 17, through the pipe 15 into the tower 11 and upwardly therein and out therefrom through the pipe 13 through the valve 16 and down the pipe 18 to the valve 17 and 'through the pipe 14: into Vthe tower 10, upwardly therein, and out through the pipe 12 and through the valve 16 to the exhaust pipe 20 to the atmosphere.

The water enters the six way acid cockV and from there flows into the pump 60 by the pipe 58 and upwardly through the pipe 66 to the top of the'towei 10 andthereinto and the weak acid liquor flows out through the pipe 61 to the acid cock and from there through the pipe 57 into the pump 59 and as weak acid liquor enters. the tower 11 through the pipe 65, then strong acid liquor flows through the pipe 62 back to the acid cock and through the pipe 03 tothe acid storage tank 64.

1t will be of course understood that if it is desired, the direction of the circulation may be reversed, that is to say, that the gas may be fed from the top and the water from the bottom in the form of a spray or other means, and also that the direction of the gas in the gas pipes may be reversed and making the tower 11 the strong acid liquor and the tower 10 the weak acid liquor, without departing in any way from the main features of the invention. i
